Composites are special materials which can provide specific individual properties such as high strength with low density or good thermal conductivity with low thermal expansion coefficient. Composites follow the constantly evolving and more complex expectations. In order to make a product with good quality, it is important to choose suitable materials and technology. In this research, powder metallurgy (PM), as one of the most common composite manufacturing technologies, was examined; which factors and mechanisms influence mostly the properties of the products. Ishikawa method was used to reveal these correlations.

Investigation of the effect of orientation and heat treatment on the stress corrosion cracking susceptibility of 7050 aluminium alloy Çevik, Gül; Doruk, Mustafa; Department of Metallurgical and Materials Engineering (2004) In the present work, the effect of variation in specimen orientation and heat treatment on the Stress Corrosion Cracking (SCC) susceptibility of 7050 aluminum alloy was investigated in 3,5% NaCl solution and under freely corroding conditions. For this purpose, Constant Extension Rate Tests (CERT) was performed on precracked Compact Tension (CT) specimens and the Direct Current Potential Drop technique was applied to measure the crack lengths. In addition to crack length versus time curves, the relationship ...
Estimation Model for Electrical Conductivity of Molten CaF2-Al2O3-CaO Slags Based on Optical Basicity BİROL, Burak; Polat, Gökhan; Saridede, Muhlis Nezihi (2015-02-01) Slag properties, such as electrical conductivity, thermal conductivity, density, viscosity, and surface tension, and the prediction of these properties play an important role in melting and metal refining. Optical basicity depends on the electronegativity of the ions of an individual oxide. This feature represents the bonding characteristics, ionization ability, ion size, and consequently the mobility of free ions inside the slag. These properties affect the electrical conductivity of slags. Therefore, in t...
Design of a high temperature erosion apparatus for testing of boiler tubes Ergün, Hüseyin; Öztürk, Tayfur; Doruk, Mustafa; Department of Metallurgical and Materials Engineering (2010) In this thesis an apparatus is designed which enables the testing of thermal power plant boiler tubes against erosion. The apparatus makes use of a tube sample directly cut from the boiler tubes and simulates conditions similar to those prevailing in boilers in lignite fired power plants. The apparatus is composed of three components; a furnace for heating the sample, a loading system which allows application of tensile stresses while allowing the rotation of the sample, and a particle blower that delivers ...
Overall shape of sintered alumina compacts Özkan, Necati (1997-01-01) The extent of the thermally induced shrinkage during sintering of nominally homogeneous ceramic compacts depends upon the green density; compacts with a low green density shrink more than those with a higher density. Therefore, shape distortions of compacts with variable density during their sintering is inevitable. The overall shapes of various sintered alumina compacts, prepared using different types of alumina agglomerates, is described. The agglomerates were prepared using organic polymer [poly(vinyl al...
Investigation of microstructure inhomogeneity in SiCp-reinforced aluminum matrix composites Gacsi, Zoltan; Gür, Cemil Hakan; Makszimus, Andrea; Pieczonka, Tadeusz (2007-01-01) The type, volume fraction, size, shape and arrangement of embedded particles influence the mechanical properties of the particle reinforced metal matrix composites. This presents the investigation of the SiC particle and porosity distributions in various aluminum matrix composites produced by cold- and hot-pressing. The inicrostructures were characterized by optical microscopy and stereological parameters. SiC and porosity volume fractions, and the anisotropy distribution function were measured to establish...
